Fungi

Question 1

heterotrophs

Answer 1

get nutrients from immediate surrounding

Question 2

autotrophs

Answer 2

get energy from sun

Question 3

yeasts

Answer 3

single-celled fungi
- eukaryotic

Question 4

hypha/hyphae

Answer 4

long thin filaments that absorb alot of water
important for sexual reproduction

Question 5

mycelium

Answer 5

network of hyphae

Question 6

mycorrhizae

Answer 6

plant-fungi symbiosis
- 80% of vascular plants partner with fungi to access nutrients in the soil
- hyphae increase the area of root system absorption

Question 7

chitin

Answer 7

building material of fungi cell walls

Question 8

spore

Answer 8

created via miosis, mechanism of dispersal for fungi
- incorporate the 1n haploid nuclei that are created during meiosis
- animal disperal
- wind dispersal
- cordyseps zombies

Question 9

saprophyte

Question 10

symbiont

Answer 10

intimate associations involving two or more species
- ex mycorrhizae

Question 11

plasmogamy

Answer 11

• 2 compatible individuals fuse their mycelia together
• forms 1 cell that has 2 haploid (1n) nuclei
• can last for decades
• produces mushrooms with gills

Question 12

karyogamy

Answer 12

• fuses together the 2 haploid nuclei to form 1 cell with 1 diploid (2n) nuclei

Question 13

Meiosis

Answer 13

cell division that reduces the number of chromosomes in the parent cell by half
- 2n–>1n
-haploid nuclei are incorporated into dispersal spores
